摘要： Methods and systems are provided for conditioning fuel for diesel engine. The system may include a fuel pump located within a fuel tank configured to pump fuel to the diesel engine. The system may also include a fuel filter located outside of the fuel tank operatively located upstream of a flow of fuel from the fuel pump. A method may include directing fuel from inside of the fuel tank through a fuel filter located outside of the fuel tank into a vacuum chamber positioned inside the fuel tank, before directing the fuel to the diesel engine.

摘要： A dual speed fuel delivery system for an internal combustion engine in an automotive vehicle includes a fuel pump, a dropping resistor connected to the fuel pump for reducing the voltage required to drive the fuel pump, and a controller for determining an optimum transition point between one of a relatively high and low speed fuel pump operation so that a controlled amount of fuel is delivered to the engine. The controller calculates fuel pressure increase across the fuel pump, determines the minimum fuel pump voltage necessary to drive the fuel pump such that a predetermined amount of fuel is supplied to the engine and determines the current draw of the fuel pump. The controller then calculates the voltage drop across the dropping resistor and compares the resulting voltage with the minimum fuel pump voltage. The controller then selectively by-passes the dropping resistor based on this comparison.
